Product Info
Introduction
Fiber grating demodulator module, the wavelength range from 1525nm to 1567nm, can be used with a variety of fiber grating sensors, through the detection of grating wavelength changes to achieve the purpose of monitoring temperature, strain, pressure and other physical quantities.
Applications
- FBG Demodulation
- FP Demodulation
- Oil & Gas (Storage Tank Monitoring, Oil & Gas Platform Structural Safety Monitoring, Pipeline Safety Monitoring)
- Energy (wind power, oil wells, pipelines, nuclear reactors, generators)
- Structural Monitoring (bridges, dams, tunnels, mines, buildings)
- Homeland Security (perimeter intrusion, hotspot monitoring, security gate monitoring)
- Spacecraft (airframes, composite structures, wind tunnels, static testing)
- Scientific Research Experiments
specificities
- Wide demodulation wavelength range, covering the entire C-band
- Rich demodulation parameters, including wavelength value, wave peak value, optical path noise floor value, etc.
- Built-in high-precision reference power supply, high demodulation accuracy and good linearity.
- Abundant communication interfaces, adopting standard Ethernet port
- Upper computer software operation is simple and convenient
- Compact structure, easy to integrate

Measurement principle
The FBG Fiber Bragg Grating Demodulator is normally polled at x pm intervals to emit light at different wavelengths, with a scanning range of 1525nm to 1567nm. The sensors are calibrated at the factory, and different wavelengths correspond to different physical quantities (as shown below). When we use the demodulator to transmit light to the sensor (grating), external influences will cause the fiber to deform and then be able to filter out different wavelengths of light. We can monitor the physical quantity by monitoring the wavelength returned by the grating sensor.
